AWS rolls the dice for faster, more efficient networking
Honey, I flattened the datacenter network
Amazon has developed a new networking topology that's up to a third faster and up to 40 percent more energy efficient than traditional hierarchical network designs.
The novel architecture, called Resilient Network Graphs (RNG), is based on random graph theory.
"Traditional networks have always been hierarchical," explained Matt Rehder, VP of global network engineering at AWS, in a recent interview. "They're sort of like an org chart where one network device will talk to the boss network device which will talk to the next boss network device and you gotta go up the chain of command in order to talk to someone else in another department."
There are reasons for that, Rehder said. Hierarchy creates structure and makes data routing rules simpler. "You don't have to know how to talk to everyone in the organization, you just talk to the person above...
